将RapidMiner流程与Java集成

我需要在Java中运行RapidMiner流程。在这个环节就像解释说：Integration of RapidMiner in Java application，将RapidMiner流程与Java集成

import com.rapidminer.Process; 
import com.rapidminer.RapidMiner; 
import com.rapidminer.operator.Operator; 
import com.rapidminer.operator.OperatorException; 
import com.rapidminer.operator.io.ExcelExampleSource; 
import com.rapidminer.tools.XMLException; 
import java.io.File; 
import java.io.IOException; 
import java.lang.Object; 

public class ReadRapidminerProcess { 
    public static void main(String[] args) { 
    try { 

     RapidMiner.setExecutionMode(RapidMiner.ExecutionMode.COMMAND_LINE); 
     RapidMiner.init(); 

     Process process = new Process(new File("C:\\Users\\Keshav\\.RapidMiner5\\repositories\\Local Repository\\lsvmtest.rmp")); 
     process.run(); 

    } catch (IOException | XMLException | OperatorException ex) { 
     ex.printStackTrace(); 
    } 
    } 
}

UPDATE：

经过多次修改，我坚持了以下错误：

可有人请与代码帮帮忙？

有什么建议吗？ – keshr3106

你看看那里有什么吗？它是开源的，或者你正在使用RM 6？（在这种情况下，我想你有支持。） –

好吧，我查看了RapidMiner论坛，做了一些修改... 但是仍然存在以下错误： '无法解析相对存储库位置'lsvmword'。进程与存储库没有关联。' 任何想法如何解决这个问题？ – keshr3106

错误消息意味着RapidMiner无法解决您的Retrieve运营商内部使用的存储库位置。原因是你已经从一个文件而不是从一个存储库加载了该进程。实际上，的过程是存储在一个存储库中，但是您已经加载它的方式，RapidMiner无法知道这一点。如果您使用此代码来指示进程，它将与存储库相关联，并且可以解析相关位置：

RepositoryLocation loc = new RepositoryLocation("//Repo/path/process"); 
Process process = new RepositoryProcessLocation(loc).load(null);
